MAX204EWE

Drivers, Receivers, Transceivers Overview

The MAX204EWE is a +5V-powered, multichannel RS-232 driver integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It features four drivers and zero receivers, designed for EIA/TIA-232E and V.28/V.24 communication interfaces. The device operates on a single +5V supply with an operating range of 4.5V to 5.5V. It supports data rates up to 120kbps and has a typical propagation delay of 10µs. The part draws 20mA of working power supply current and functions within a temperature range of -40°C to +85°C. It is housed in a 16-pin Wide SO package.

Drivers, Receivers, Transceivers Feature Summary

• Integrates charge pump circuitry to generate required voltage levels from a single +5V supply
• Provides four independent RS-232 drivers for multi-channel communication
• Maintains ±5V output signal levels compliant with EIA/TIA-232E specifications

Drivers, Receivers, Transceivers Applications

• EIA/TIA-232E communications interface applications
• V.28/V.24 communications interface applications
• Battery-powered equipment requiring single-supply operation

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E' indicates the extended industrial temperature range (-40°C to +85°C) compared to the commercial 'C' variant. Confirm the 'W' suffix corresponds to the Wide SO-16 package dimensions. Ensure the '+' designation confirms lead-free and RoHS compliance status before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when four transmitter channels are required without receiver functionality. It is suitable for designs needing full-duplex capability via external receiver integration or where only transmission is necessary. Verify that the 120kbps maximum data rate meets system requirements and that the 16-pin Wide SO footprint fits the PCB layout constraints.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX200-MAX209 family of +5V RS-232 transceivers. Unlike other members such as the MAX202 which includes both drivers and receivers, the MAX204 specifically provides four drivers and no receivers. This configuration distinguishes it within the series for applications focused solely on signal transmission.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers include MAX204CWE+ (commercial temperature range) and MAX204CPE+ (Plastic DIP package). These parts share identical electrical characteristics and pinouts but differ in temperature rating or physical package form factor.
